Last week one of our group mates was fixing a flat off the side of the road. In a ten-minute span three or four groups passed us and every one of them asked if we needed help. So civility isn't entirely lost.
Just yesterday we passed a group of women cyclist on the side of the road just as we began our ride. Naturally we asked if they needed help. To our surprise they said yes. So we stopped to help them change a flat. It delayed our ride for about ten minutes, but no biggie. I was both repairing and educating them on how to do a proper fix. They had trouble pulling off the tire from the wheel. They weren't quite sure how to use the CO2 cartridge. They were simply trying to install the new tube without inspecting the tire for the puncture. Turned out there was a long metal shard embedded in the tire and would have caused a second puncture almost immediately.
Afterwards one of them women tried to stick a $10 bill into my hand, for our coffee break, she said. We declined. Her gratitude was enough.
